Abstract

PURPOSE:To prevent creation of noise, by constituting a device such that, in an air conditioner with an inner air and outer air intake selecting device, when inner air intake is shifted to outer air intake by means of a car speed signal and an inner air and outer air selecting signal, a motor is driven by power proportional to a car speed. CONSTITUTION:By connecting a manual switch 23 to an outer air intake terminal 25, a power-operated motor 14 is electrically connected through an outer air intake contact 21 and a resistor 27, and is run until a moving contact 22 reaches B' to bring a damper 11 to an outer air intake position B. When the manual switch is connected, in a similar manner, to an inner air intake terminal 26, the motor 14 is coupled to an inner air intake contact 20 and a resistor 28, the motor 14 is coupled to an inner air intake contact 20 and a resistor 28, the motor 14 is run at a low speed until the moving contact 22 reaches position A', and a damper 11 is brought to an inner intake position A. In this case, if a car speed 29 exceeds a reference value, continuity of a transistor 32 short- circuits the resistor 28, a current to the power-operated motor 14 is increased, and the motor 14 is run at a high speed. This causes the motor to rotate at a speed proprotional to a car speed, resulting in prevention of creation of noise.
